Added compatibility for PZK Vanilla Vehicles so filling the fuel tanker truck will cost funds. These things are huge, and will drain your credit cards quite well...
Moved the mod compatibility code to its own .lua file instead of in the general PayAtThePump .lua file.
Updated the other mod compatibility for build 42. The check for if a mod is available now correctly checks the mod name with the '\' char on the front.

Updated the B41 version to match the B42 releases public functions, so modders can update their B41 version mods to integrate with Pay and Pump.

Updated code so the local functions are now available for modders to use.

Updated for B41

Added a sandbox option to automatically find funds (credit cards and Money) in your bags in your inventory. By default this is off.
When it is on the mod will look in your main inventory first and then bags to find credit cards. When the credit cards in your main inventory are used up, it will use the ones in your bags. If it can't find any credit cards it will use the first Money it can find.
This means if you have Money in your main inventory and a credit card in your backpack, it will use the credit card before the Money.

Updated for B42. The balance is now appended after the cardholder's name.

Updated the max cost for fuels to 10000.0

Updated the 3rd Party Patch to also patch for the PZK vehicles mod, as it uses the same code as Treads.

Updated sandbox options for the credit card initial value ranges. Min and max now have the same range, so it is possible to set a fixed value by setting min and max to the same number.
Added checkboxes to turn on/off Money and Credit Cards. Note that turning off both will prevent anyone from getting gas :)

Added check so the Treads compatibility patch does not error if the FuelAPI is not included in the mods.
